Abstract

A resin composition comprises a polyether ether ketone, an aromatic polysulfone, a polyetherimide, and a fibrous filler.

Claims

exact text as granted — not AI-modified
1 . A resin composition comprising a polyether ether ketone, an aromatic polysulfone, a polyetherimide, and a fibrous filler. 
     
     
         2 . The resin composition according to  claim 1 , wherein the content of the polyetherimide is less than 40% by mass based on a total content of the polyether ether ketone, the aromatic polysulfone, and the polyetherimide. 
     
     
         3 . The resin composition according to  claim 1 , wherein a content of the polyether ether ketone is 25% by mass or more based on the total content of the polyether ether ketone, the aromatic polysulfone, and the polyetherimide. 
     
     
         4 . The resin composition according to  claim 1 , wherein a melt viscosity ratio between a melt viscosity of the polyether ether ketone at 400° C. and a melt viscosity of the aromatic polysulfone at 400° C. (a melt viscosity of aromatic polysulfone/a melt viscosity of polyether ether ketone) is 1.5 or more and 6 or less. 
     
     
         5 . The resin composition according to  claim 1 , wherein a content of the fibrous filler is 10 parts by mass or more and 100 parts by mass or less based on 100 parts by mass of the total content of the polyether ether ketone, the aromatic polysulfone, and the polyetherimide. 
     
     
         6 . A resin composition comprising a polyether ether ketone, an aromatic polysulfone, a polyetherimide, and a fibrous filler, wherein openings generated by contacting N-methylpyrrolidone with a cross section of a molded body made by using the resin composition have an average circle-equivalent diameter of 0.22 μm or less. 
     
     
         7 . A molded body produced by using the resin composition according to  claim 1 .
